Ipad App Dashboard forbidden

I have just got an ipad and downloaded the wordpress app. Everything seems to work except for the Dashboard feature. I can view my site, see pages, comments and posts in the viewing screen next to the tab However when i hit the dashboard tab the viewing screen loads a message saying
' Forbidden
you do not have permission to access /wp-login.php on this server.

Additionally, a 403 Forbidden error was encountered whilst trying to use an ErrorDocument to handle the request.'

nope not yet. As it is a self hosted out blog i wonder if i need some code to put in a file on my back end to authorise the ipad? that is closest i have come but very cautious about putting anything into the cpanel as i dont fully understand coding.
